PRODUCT DESCRIPTION
E​​​​​​XGN15-12/24 series of unit-type metal-enclosed switchgear lakes FLN□-12/24 type SF6 load break switch as the main switch,and  the  entire  cabinet is  air-insulated,suitable  for  distribution  automatic,compact  and  expandable  metal-enclosed loop  network  switchgear.It  has  features  of  simple structure,flexible  operation,reliable  interlocking,easy  installation  and     so on.It can provide satisfactory technical solutions for a variety of different applications and different user requirements    which comply to IEC 62271.
XGN15-12/24 series of unit-type  metal-enclosed switchgear takes  FLN36-12/24  or  produced  by  our company or SFG SF6-lype load switch produced by ABB company as the main switch,it can also equip VS1 type,VD4/S type,ISM type     vacuum circuit breaker or HD4/S5 SF6 circuit breaker according to the needs of users.Load break switch and circuit breaker can  be  manually or electrically operated,and can achieve  power distribution automation when  being  equipped with  optional  electric  operating  mechanism,PT,CT,FTU  and  communication  devices.
The Technical Specifications of this XGN15-12/24 Switchgear define its electrical and mechanical parameters for medium-voltage distribution networks. The Fixed Type Metal Clad Switchgear utilizes FLN0-12/24 type SF6 load break switch as the main switch, with the entire cabinet being air-insulated, making it suitable for distribution automation and compact, expandable metal-enclosed loop network switchgear applications. This SF6 Load Break Switch Cabinet features a simple structure, flexible operation, reliable interlocking, and easy installation, providing satisfactory technical solutions for various applications and user requirements in compliance with IEC 62271. The XGN15-12/24 Switchgear can be equipped with FLN36-12/24 SF6 load switches produced by our company or ABB, and can also incorporate VS1, VD4/S, ISM vacuum circuit breakers, or HD4/SF6 circuit breakers according to user needs. This Fixed Type Metal Clad Switchgear supports manual or electric operation, and can achieve power distribution automation when equipped with optional electric operating mechanisms, PT, CT, FTU, and communication devices. Each SF6 Load Break Switch Cabinet is rated at 12kV and 24kV with 630A current, featuring rated short circuit withstand current of 630A and rated peak withstand current of 50kA.
